1. The problem statement: A stepladder consists of two halves, hinged at the top, and connected by a tie rod that keeps the two halves from spreading apart. In this particular instance, the two halves are 2.50 m long, the tie rod is connected to the center of each half and is 70.0 cm long. An 800-N person stands 3/5 of the way up the stepladder, as shown in the figure. Neglecting the weight of the ladder, and assuming that the ladder is resting on a smooth floor, what is the tension in the tie rod?

2. Homework Equations
ƩFx=0
ƩFy=0
Ʃtorque=0
3. The Attempt at a Solution :
I know I should look at the ladder as if it were in 2 separate pieces but I have no idea how to start or what to look at.
I also tried drawing free body diagrams for each but it confuses me even more
